Open race v2 is an open source ESP32 PCB design by teehee567, published on GitHub. It is a 8-layer board measuring 90.5 × 49.5 mm, with 329 components from 107 distinct parts.
Its main chip is the ESP32-C6-MINI-1-N4, from the ESP32 family. Other key parts include the AP33772SDKZ-13-FA02, STM32N657X0H3Q, APS512XXN-OB9-BG, TPD8S300ARUKR and IS25WP512M-RHLE. By type, the board carries 163 capacitors, 98 resistors, 22 ICs, 14 diodes, 8 inductors and 7 switches.
It belongs with the rf & radio, iot & wireless and power & battery designs in this gallery.
From the project
gnss module collecting track data
Aevia is a DIY, battery powered lap timer and track data logger. The current hardware is the V2 Mini, a compact board that combines multi-band GNSS, a 6-axis IMU, local storage, a display interface, physical controls, and wireless connectivity.
Uses very very high end sensors, UM980, SCH16T-K01
The goal is to build something in the same general space as a Garmin Catalyst, but at a lower cost and with more control over the hardware, raw data, and software. Recorded data should also remain useful outside the device, with export to proper desktop analysis tools.

Open race v2: common questions
What microcontroller does the Open race v2 use?
The Open race v2 is built around the ESP32-C6-MINI-1-N4, from the ESP32 family.
How big is the Open race v2 PCB?
The Open race v2 measures 90.5 × 49.5 mm, has 8 copper layers and is 1.6 mm thick.
How many components are on the Open race v2?
329 components, from 107 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Open race v2 design files?
From the teehee567/Aevia repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Open race v2 design in my own project?
The repository has no license, so all rights stay with teehee567. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Open race v2 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
